Seriously, that is my answer. When a study reports that diets high in some component (call it factor x) are associated with some good outcome, they're looking at diets naturally high in factor x. Studies attempting to get the same effects via supplements just don't work.

If you have a specific deficiency, a supplement may be called for. Otherwise, it's better to change your diet so you're eating/drinking foods that naturally contain not only factor x, but also factors y and z that might be just as important, and you're not creating an imbalance of way too much x that might lead to other problems.

Plus, tastier and better quality of life with real foods and teas instead of pills that might or might not even contain factor x.

+1When I first started drinking tea, I didn't care for greens either. I drank mostly blacks. Then I started drinking oolongs. My taste for oolong got greener and greener. Then I tried green tea again. These days I like all kinds of tea.Try easing yourself into them.
